Characteristics of cold-rolled and hot-rolled aluminum sheets
The cold-rolled aluminum plate is machined from the hot-rolled aluminum sheet at a normal temperature. Cold rolling is compared to cold rolling, the mechanical properties are relatively poor, the hardness is too high, so the cold-rolled aluminum plate is used for mold, and hot-rolled aluminum plate is deep, and the bending performance is better, тому підходить для глибокої обробки.

How do you distinguish between cold-rolled aluminum plates and hot-rolled aluminum plates?
- Different production processes: Cold rolling is made by casting machine (8mm thickness) made by cold rolling machine, hot rolling has aluminum ingot (400-500mm heated thickness) made by hot rolling mill at high temperature
- Different raw material supply: the difference between the two is that the blank supply is different. The hot-rolled blank casting aluminum ingot is heated and rolled into rolls for cold rolling, while the cold-rolled blank is cast and rolled into rolls for cold rolling
- Different performance: hot rolled aluminum plate surface quality, механічні властивості, пластичність, хороший ефект окислення. В той самий час, the aluminum plate is generally processed by an aluminum plate, which is naturally affected by the performance of the aluminum plate
- Різне використання: cold-rolled aluminum plate is used for mold, the hot-rolled aluminum plate is suitable for stamping and drawing
